I am sure, I hope, you are aware your prayer life is highly unusual among all Christians and cannot be assumed to be the "standard" for the entire group.
Bless you.
Next time you see the flowers in front of the image of a saint recall that wreathe that is placed before the tombs of the Unknown, or even the flowers on a mether's grave. It has the same meaning
I hear what you are saying but to me it seems to be more than a remembrance. It would be like placing flowers in the arms of a statue of a mother or soldier, kneeling on an alter before them, and praying to someone who has died, which I think somewhere in the Bible, God tells us not to do. I'm looking for it.
Go to Washington and see the people leaving flowers and kneeling in honor of their fallen loved ones at the Vietnam memorial. Heck, go to any cemetery.
People leave offerings of flowers. This doesn't equate to worship.
